Surprised this issue hasn't called a recall of some kind. Obviously there is a problem with the s/c and it needs to be addressed...

Just my thoughts on this...

most of the problems have been due to erroneous installs. You only hear about the bad

I believe is 12 months or 12000 miles on parts only if you didn't have it done at a dealership.

Yea that sounds about right. Man I hope my s/c doesn't go bad on me since its not stock even though I got it installed at the dealer.

If its not stock and something does happen you better make it stock before going back to the dealer, or else they might look the other way

I hate warranties sometimes...

_________________
Thats correct I see a few posts where the install is the blame I can tell you in my case I did my own install and it was done to the book every bolt was torqued to spec and in the proper order. I done this myself because my dealer or neighboring dealers hadnt even seen one and didnt have the tools to flash the ECU so I ordered it from Longo Toyota and mailed them the ECU to have it flashed

Default heres the deal My opinion

I have looked at the design of the Vortech blower talked with Vortech and they really wont comment because its sold by TRD
I checked part numbers on the original seals and they are single lip seals that are not going to take any pressure the bottom of the S/C has a 1/2 inch return line going directly into the oil pan and with the PCV system that is on the 2.4, which is nessasary to meet emissions in all states it is under pressure at all times untill atmospheric pressure or above is reached. With this design there is pressure on the seals in the S/C at all times except under hard acceleration or boost with the pressure in the 1/2 return line It is my opinion that it has to give some restriction to the gravity fead oil return line. I am going to check the pressure in the crankse this week end so I have some accurate numbers to supply.
My S/C was not leaking bad and is under warranty but I have elected to try some things my self. I put a temporary oil catch can on the engine removing the PCV valve
This way the crankcase runs at atmospheric pressure all the time. I have had it this way for 125 miles now and there is no sign of oil on the engine at all.
I also had my BOV in backwards which I corrected but I cant see how that could have any effect.
I am going to use a design which will actually keep the crankcase at negetive pressure using a catch can and deverter in the exhaust.
I will post my findings
Keep in mind that if you have a damaged or blown seal this is not going to fix anything
But it is of my opinion and others in the boosted community that a boosted engines crankcase should not run under pressure. ie PCV system
